High-harmonic generation (HHG), a typical nonlinear optical effect, has been actively studied in electron systems such as semiconductors and superconductors. As a natural extension, we theoretically study HHG from electric polarization, spin current, and magnetization in magnetic insulators under terahertz or gigahertz electromagnetic waves. We use simple one-dimensional spin-chain models with or without multiferroic coupling between spins and the electric polarization, and study the dynamics…

This paper theoretically proposes an experimental method of measuring the magnetic oscillation in a magnetic-order-resolved way by using the azimuthal cylindrical vector (CV) beam, an example of topological lightwaves, and argues that this characteristic focusing property and the discrepancy in the relaxation timescale between conduction electrons and localized magnetic moments allow it to develop the nonequilibrium analogue of the Magnetic oscillation measurement.
